Entanglement Swapping with Misty States

The misty states formalism introduced by Terry Rudolph in 2017 is an alternative pedagogical approach that acts as a bridge to the standard quantum computation curriculum. We have shown elsewhere how it works, by using it to prove and demonstrate: phase kickback, Bernstein-Vazirani, Deutsch-Josza, the Grover quantum search, superdense coding, teleportation and the GHZ game. Here we use it to communicate entanglement swapping (also known as the teleportation of entanglement).
